Ever since I installed this new 480GB SSD Plus drive a few months ago it seemed like if there was heavy disk activity (i.e. unzipping large files) Windows performance would take a dive. More recently I noticed games loading much more slowly than before (i.e. No Man's Sky loading shaders from disk counts up to 100% in minutes instead of in about 30 seconds). Did some drive tests with Crystal Disk Mark and I'm getting 22/26MB/s speeds which is horrible. Used to get over 500MB/s with my Samsung SSD.
SSD Dashboard is up to date, Windows up to date, Dell drivers all up to date. Firmware up to date (UG4500RL). Ran TRIM. Rebooted computer. I think it's time to return this drive. I lost faith in SanDisk years ago with failed USB keys and memory cards but thought I'd try again when this drive was on sale after Christmas. I've never had performance issues with any other SSD (Samsung, Crucial, WD, Kingston, etc.).

I have never experienced any SSD showing performance that low. How long has it been installed? was it performing correctly before? what are the specs of the system it is in? what driver are you using?

Me neither. The Samsung before this was around 500MB/s. I didn't test this one after installing a month or two ago; it didn't seem slower. I'm going to have to get an RMA process going with SanDisk. I'm using a Dell Optiplex 7010, Core i7, 16GB RAM. I've used various SSDs from Kingston, Samsung, OCZ in this system and they've all been lightning fast.
